Uni-Wireless-Sync: wireless control toolkit for TL LCD fan hubs

UWS CLI

Warning: This is an unofficial implementation; use at your own risk.

Overview

UWS CLI provides command-line utilities for managing Uni Fan Wireless controllers, L-Wireless receivers, and LCD panels. Each command re-opens the required USB or RF device so no background daemon is left running, and lower-level HID/USB errors are surfaced directly to simplify scripting.

Supported Hardware

• UNI FAN TL wireless LCD panels
• UNI FAN TL wireless fan hubs (non-LCD)

Other Uni Fan series are currently not supported.

Features

• Discover TL LCD USB devices and 2.4 GHz wireless fan controllers.
• Query LCD firmware and handshake data.
• Send JPEG frames or apply control settings (mode, brightness, rotation) to the LCD.
• Keep the wireless TL LCD awake by emitting periodic handshakes.
• List wireless fan hubs with metadata (MAC, master MAC, channel, device type, fan speeds, PWM targets).
• Send one-shot PWM commands to TL wireless fans over the 2.4 GHz dongle.
• Bind or unbind wireless hubs against the active master controller.
• Toggle motherboard PWM sync mode for one hub or every bound hub.

Roadmap

• Broadcast static RGB payloads to wireless hubs (CLI command not yet implemented).

Installation

pip install uwscli
# optional image helpers
pip install uwscli[images]

python -m venv .venv
source .venv/bin/activate
pip install -e .
# or include dev extras
pip install -e .[dev]

Usage Examples

# Enumerate connected devices
uws lcd list
uws fan list

# Display operations
uws lcd info --serial <usb-serial>
uws lcd send-jpg --serial <usb-serial> --file assets/sample_lcd.jpg
uws lcd keep-alive --serial <usb-serial> --interval 5

# Fan hub operations
uws fan set-fan --mac aa:bb:cc:dd:ee:ff --pwm 120
uws fan bind --mac aa:bb:cc:dd:ee:ff
uws fan unbind --mac aa:bb:cc:dd:ee:ff
uws fan pwm-sync --all --enable
uws fan pwm-sync --mac aa:bb:cc:dd:ee:ff --disable --fallback-pwm 120

uws lcd list prints JSON rows that include a serial field—copy that value when invoking other LCD subcommands.

Command Reference

• uws lcd list – enumerate TL LCD devices and show their USB serial numbers.
• uws lcd info --serial <usb-serial> – read firmware and handshake data.
• uws lcd send-jpg --serial <usb-serial> --file <image.jpg> – stream a JPEG asset.
• uws lcd keep-alive --serial <usb-serial> [--interval seconds] – emit periodic handshakes to prevent the wireless panel from dimming.
• uws lcd control --serial <usb-serial> [--mode show-jpg|show-app-sync|lcd-test] [--index N] [--brightness 0-100] [--fps N] [--rotation 0|90|180|270] [--test-color R,G,B] – send an LCDControlSetting payload.
• uws fan list – fetch a snapshot of bound wireless devices via the RF receiver.
• uws fan set-fan --mac <aa:bb:..> --pwm <0-255> – send a single shot PWM update to the matching wireless hub using the RF sender.
• uws fan pwm-sync --all|--mac – enable or disable motherboard PWM sync for bound hubs.

Dependencies

• hidapi (via hid) for TL LCD HID access.
• pyusb for the RF sender/receiver WinUSB endpoints.
• pycryptodomex for the DES-CBC transport used by the wireless LCD hub.
• Pillow is optional for JPEG frame validation.

Each command expects the TL LCD USB display (vendor 0x04FC or 0x1CBE) and the wireless transmitter/receiver pair (vendor 0x0416) to be attached when the command executes.

Linux udev Permissions

Grant non-root access to the TL wireless dongles by adding /etc/udev/rules.d/99-tl-wireless.rules with:

# Winbond SLV3RX_V1.6 (receiver)
SUBSYSTEM=="usb", ATTR{idVendor}=="0416", ATTR{idProduct}=="8041", MODE="0666", GROUP="plugdev"
SUBSYSTEM=="usb_device", ATTR{idVendor}=="0416", ATTR{idProduct}=="8041", MODE="0666", GROUP="plugdev"
SUBSYSTEM=="usb_interface", ATTRS{idVendor}=="0416", ATTRS{idProduct}=="8041", MODE="0666", GROUP="plugdev"

# Winbond SLV3TX_V1.6 (transmitter)
SUBSYSTEM=="usb", ATTR{idVendor}=="0416", ATTR{idProduct}=="8040", MODE="0666", GROUP="plugdev"
SUBSYSTEM=="usb_device", ATTR{idVendor}=="0416", ATTR{idProduct}=="8040", MODE="0666", GROUP="plugdev"
SUBSYSTEM=="usb_interface", ATTRS{idVendor}=="0416", ATTRS{idProduct}=="8040", MODE="0666", GROUP="plugdev"

Reload the rules and replug the dongles:

sudo udevadm control --reload
sudo udevadm trigger
